| 1. | Sonic point position and critical pressure ratio in micro nozzles 微喷管内声速点位置及临界压比 |
| 2. | Critical pressure ratio 临界压力比 |
| 3. | The other is that the critical pressure ratio in microchannels is different from that in macroflow greatly 本文将这一现象定义为亚堵塞现象,并将对应的压比定义为亚堵塞临界压比。 |
| 4. | Measuring the mass flow rate in relation to outlet pressure , the critical pressure ratio is defined as the criterion for whether the choking phenomenon takes place 此时,其流速和流量将保持一致且不受后续管路条件不同的影响,从而可起到均化喷煤量的作用。 |
| 5. | The relationship between critical pressure ratio and solid / gas ratio is thus found to provide a reference for choosing appropriate jet pipes and conditions for their applications 实验测定了质量流量与出口压强的关系,定义了临界压强比可作为判定壅塞发生与否的依据,并找出了临界压强比与固气比之间的变化规律,给出了实用喷管的选择依据和使用条件。 |
